This Set of 4 tensor rings is very powerful. This is because when a tensor ring sits inside another bigger one. The outer ring amplifies the inner 1. So you can imagine the power of this set of 4. They can be fastened together and used to help with healing on specific parts of the body or the body as a whole.
Or they can be used separately. For instance, the smaller one can be carried in your pocket or worn around your neck. These tensor rings are all based on the sacred cubit the sizes are. A quarter cubit, a third of a cubit, two-thirds of a cubit, and a whole cubit.
